Many everyday tasks that children do—such as getting dressed, cutting with scissors, riding a bike, or even opening a lunchbox—rely on an important foundational skill: bilateral integration.
While it might look simple on the outside, using both sides of the body together in an organised way is a complex skill. It develops over time through movement and plays a massive role in how children learn, play, and become independent.
Signs Your Child Might Be Struggling
Parents often notice that their child avoids certain activities, struggles with tasks that require two hands, or finds school tasks like writing or cutting particularly difficult. These challenges are often not due to a lack of motivation or interest; they are often linked to the body’s ability to coordinate both sides of the body together.
In this blog, we’ll explain what bilateral integration is, why it matters for everyday function, and practical ways you can support your child at home through play.
What is Bilateral Integration?
Bilateral integration is the ability to use both sides of the body together in a smooth and coordinated way to complete a task. This skill develops gradually through movement experiences in early childhood, starting with fundamental activities like crawling, climbing, and active play.
There are three main types of bilateral integration that we look for in occupational therapy:
1. Symmetrical Bilateral Integration
This occurs when both sides of the body perform the same action at the same time. This is the first type of coordination a child typically masters.
- Examples include: Clapping, jumping with two feet, or catching a large ball with two hands.
2. Reciprocal Bilateral Integration
This is when both sides of the body move at the same time, but in alternating patterns. This requires more advanced rhythm and timing.
- Examples include: Crawling, walking, climbing stairs, or peddaling a bike.
3. Asymmetrical Bilateral Integration (The “Helper Hand”)
This is the most complex level. It involves one side of the body performing a primary task while the other side acts as a “helper” to stabilise or assist.
- Examples include: Holding a piece of paper with one hand while cutting with the other, or stabilising a bowl while stirring.
Why It Matters for Your Child’s Independence
Without strong bilateral integration, a child may appear “clumsy” or get frustrated with daily tasks. Developing these “bridge-building” connections in the brain is essential for:
- Fine Motor Skills: Writing, zipping up a jacket, and using cutlery.
- Gross Motor Skills: Running, swimming, and sports.
- Cognitive Development: Research shows that crossing the midline and using both sides of the body helps both hemispheres of the brain communicate, which is vital for reading and logic.
How to Support Bilateral Integration at Home
The best way to build these skills is through purposeful play. Here are some simple, fun activities to try:
- Balloon Volleyball: Keeping a balloon in the air requires quick, two-handed movements.
- Playdough Fun: Pulling, rolling, and using a rolling pin are excellent for symmetrical coordination.
- Animal Walks: Encourage “bear crawls” or “crab walks” through the lounge room to work on reciprocal movement.
- The “Helper Hand” Challenge: Practice activities like tracing stencils or using a ruler, where one hand must hold still while the other moves.
When to Seek Support
If you notice your child consistently avoids using their “helper hand,” struggles to cross the midline of their body, or finds physical play very tiring, an Occupational Therapist can help.
At Upside Down Therapy, we focus on the “why” behind the struggle. We use play-based, sensory-rich strategies to help your child find their balance and build the confidence they need to tackle everyday tasks with both hands!
